I couldn't get Act to function, so Tech support said to disable DEP under Advanced System Performance Settings Data Execution Prevention. However, when the radio button was set to 'Turn on DEP for essential Windows programs and services only” radio button, Act would not function.

Data Execution Prevention (DEP) is one of those ‘blursed’ things. It’s a blessing most of the time when it does its job and doesn’t interfere, but cursed when it does interfere.
Let’s look at DEP and how to configure it, or turn DEP off, depending on your needs.
What Is DEP & What Does It Do?
According to Microsoft, DEP is :
“…a set of hardware and software technologies that perform additional checks on memory to help prevent malicious code from running on a system.”
Dell simplifies it a bit and tells us that DEP
“…can help protect your computer by monitoring your programs to make sure that they use system memory safely.”
What does that mean? There are certain areas in the computer’s memory which aren’t intended to have code running in them, but sometimes code does run there.
Usually, the code that will run there is malicious. DEP will monitor those areas and if it sees something going on in those areas it will shut it down. If you want to get in-depth about how it works, read Microsoft’s detailed description of Data Execution Prevention.
So Why Does DEP Cause Problems?
Even today, computers are dumb. They cannot reason, they can only use the most basic of logic. Plus, that logic is put into them by humans so computers also get our mistakes put into them. https://newpod541.weebly.com/this-day-aria-colt-version-download.html.
Sometimes, good programs will wander off into the areas that DEP monitors and work in those spaces.
When this happens, DEP will sometimes shut the entire program down and let you know via an error message. But sometimes DEP will just cause the program to run very poorly and there won’t be anything obvious to tell you why.
What Programs Have Problems With DEP?
Programs that conflict with DEP are typically older programs or built on old codebases. A lot of Enterprise Resource Planning (ERP) software is built on codebases that go back to the 1970s. There was no DEP then, so the program will go into areas that DEP patrols.
64-bit programs were created after DEP was well established, so they were developed to comply. Most programs that conflict with DEP will be 32-bit programs.
Non-Microsoft programs that interact with Windows Services heavily or run their own Windows Services may be tripped up by DEP. If that is the case, the vendor will recommend to completely turn off DEP.
For the home user, old games that are 32-bit, and some emulators for playing even older games, are the most likely to conflict with DEP.
Old device drivers or drivers downloaded from unofficial sources may also trigger DEP errors. Only download drivers from the hardware manufacturer or Microsoft, and update your drivers regularly.
How Do I Know If DEP Is The Problem?
You may have to go into Event Viewer and sift through the logs for Event ID 1000. If you find one, it may look like this: https://vokezx.weebly.com/you-cannot-download-office-for-mac-2016.html.

How To Configure Or Turn Off DEP
In Windows 10, DEP defaults to the setting Turn on DEP for essential Windows programs and services only. Most of the time, this is sufficient. It means that the majority of your programs will be ignored by DEP.
But if DEP helps protect the computer and it doesn’t have a performance hit, you may want to select Turn on DEP for all programs except those that I select. Then if you find a program that has a problem with DEP, we can add it as an exception. Let’s look at how to do that.
Turn DEP Completely Off
If you want to turn DEP completely off, we advise only doing that as part of troubleshooting an issue. DEP is there for your protection.
Since it’s something that isn’t advised, there isn’t a good point-and-click way to do it. Let’s look at how we can turn off DEP.
bcdedit.exe is a Windows utility for editing boot configuration data, hence bdcedit.
/set tells bcedit to set an option value entry in the boot configuration.

{current} tells becedit to work with the boot configuration being used right now.
nx is short for no execute and is the setting name for DEP in the boot configuration.
AlwaysOff is self-explanatory.
Turn DEP On For Everything
To turn DEP on for absolutely everything, the process and command is like above.
After turning DEP to being always on or always off, it CANNOT be changed via the Data Execution Prevention tab in system settings.

Set DEP Back To Default Behavior
To set DEP behavior back to default and make it manageable again via system settings, do the following.
To DEP Or Not To DEP
We recommend leaving DEP on its default setting of Turn on DEP for essential Windows programs and services only, unless it’s necessary to change it to troubleshoot problems that may be DEP-related.

Data Execution Prevention![]()
In Windows XP Service Pack 2 (SP2), Microsoft introduced Data Execution Prevention (DEP). DEP is a processor feature that prevents execution of code in memory that is marked as data storage. This limits the 'attack surface', specifically for the so-called 'buffer overrun' vulnerabilities, where an attacker would typically overrun a buffer with code, and then executing this code. Unlike a firewall or antivirus program, DEP does not help prevent harmful programs from being installed on your computer. Instead, it monitors your programs to determine whether they use system memory safely. DEP isn't the 'end all', but rather just another added layer of protection.
Hardware-enforced DEP
Currently, the only x86 processors that support No-Execute functionality are the AMD 32/64-bit Opteron and Athlon-64. Other processor manufacturers are looking to incorporate DEP support in their processor line. The Intel Itanium family of 64-bit processors (IA-64 architecture) support DEP. According to Intel, they will add NX ('No Execute') functionality to all desktop processors by late Q3, 2004, and mobile products by late Q4, 2004.
Software-enforced DEP
Windows XP SP2 uses software-based DEP which monitors your programs to determine whether they use system memory safely. To do this, DEP software marks some memory locations as 'non-executable.' If a program tries to run code from a protected location, DEP closes the program and notifies you. This action occurs even if the code is not malicious. DEP prevents code from being run from data pages such as the default heap, stacks, and memory pools.
DEP compatibility issues can occur for both programs and drivers. Symptoms of a failure that is related to DEP support would include access violations. A dialog box indicates that a program has failed because of DEP. The dialog box contains a message that is similar to the following:
From the initial error interface, you can click Advanced to access DEP configuration settings (you can also access these by going to Windows XP's Control Panel > Performance and Maintenance > System. Choose the Advanced tab, and click the Settings button under Performance. DEP settings are on the Data Execution Preventiontab). Tamil ringtones for android phone free download. You can add an exception for the failing program.
The Data Execution Prevention configuration offers you the following options:

By selecting one of these options, you can exclude one or more programs or configure DEP settings for the whole computer. Setting the option to turn off DEP adds a switch to the Boot.ini configuration file for the Windows installation that you are currently running.
The Boot.ini file switches are as follows:
When the Boot.ini file is set to either /noexecute=AlwaysOff or /execute, Physical Address Extension (PAE) mode is not invoked.

Note: Microsoft recommends that you not disable DEP globally. This would put the computer in a less secure state. Mojave dmg download.
